Biology:

Proceratium species are mostly hypogeic (subterranean) ants, apparently specialized as predators on eggs of spiders and other arthropods.

Identification:

Worker: eyes very small or absent; mandible multidentate and not overhung by clypeus; antennal sockets largely exposed in full-face (frontal) view of head; pronotum fused to mesonotum; abdominal tergite 4 strongly arched and recurved ventrally, the corresponding sternite very reduced in size.

Notes:

A single species of Proceratium has been recorded from California.
